Recent Research Trends in Carbon Fiber Tow Prepreg for Advanced Composites

Abstract

Tow Prepreg is the intermediate material for filament winding process that has been "pre-impregnated fiber tow" with resin system. As "dry filament winding" process emerges as a reliable alternative to conventional filament winding (called "wet filament winding") process, interest in tow prepreg as a material for dry filament winding is rising as well. In this article, we have reviewed the recent research trends in carbon fiber tow prepreg for high-performance rocket motor cases, fuel tanks for hydrogen vehicles and other high-quality commercial pressure vessels.

Analysis and prediction of the width of spreading carbon fiber tow based on gray system theory

“…In this article, the residual error test is used. The average relative error MAPE of the gray prediction system is calculated, as shown in Equation (10).…”

“…7 Raw silk is processed into carbon fiber tow by dipping, widening, drying and winding, and the dimensional quality is closely related to the speed and tension during the fiber-drawing process. [8][9][10] Combining carbon fiber tow production experience and field investigation of the carbon fiber tow production line, there are many uncertain factors in the production process. Under the premise of fixed ultrasonic frequency and amplitude, the tension of spreading fiber and speed of spreading fiber have the greatest influence on carbon fiber tow size parameters and are not related by a simple linear combination law.…”
